1 IMPROVEMENT. IN E NVELOPES.

Specification forming part of Letters Patent No. 189,189, dated April 3,1877; application filed February 17, 1877. I

To all whom it may concern:

Beit known that I, RODERICK CHRYsLER CARTER, of Kingston, in the countyof Frontenac, Province of Ontario, Dominion of Canada, have inventedanew and useful Improvement in Envelopes; and I do hereby declare thatthe following is a full, clear, and. exact description of the same.

This invention has for its object to provide an enve1ope,'which shall beso constructed that it may be conveniently opened and reclosed, andshall hence be adapted for use in the postal service, and for filingoffice documents; also, for containing flour, confections, or othermerchandise to which frequent access is required, for examination orother purpose.

My improved envelope, or bag, has a flap or flaps, at one end or side,such flap or flaps being fastened by a tongue or buckling device, in themanner hereinafter described.

Referring to accompanying drawing, forming part of this specification,Figure 1 is a plan viewof an envelope constructed according to myinvention. Fig. 2 is a modification.

The envelope A is represented adapted to be permanently closed at oneend, b, and provided with a temporary or detachable fastening at theother end, 0. The said fastening consists in part of a folding flap, D,or strip E, formed in one piece with, or otherwise permanently attachedto, the body of the envelope, and provided with slots; also,'of atongue,

f, formed in one piece with theflap D, and which, when the flap isclosed, is inserted through a loop, g, formed by slitting the back ofthe envelope at a point coincident with the slot'or openingein the flap.The tonguef may be a lateral extension of the folding flap D, as shownin Fig. 2, or it may be formed by cutting out a portion of the broadflap D, as shown in Fig. l.

In either case the operation and result are the same, since the tongueserves to connect or attach the flap D, or strip E, (as the case maybe,) to the body of the envelope when inserted through the loop g, drawnup through the opening 0, and thus closing the end 0 of the envelope.The tongue may be readily withdrawn from the loop to release the strip Dor flap E, and allow the envelope to be opened for the purpose of accessto, or inspection of, its contents, as occasion may require.

What I claim is The combination, with the body of the envelope, havingthe loop g of the flap or strip, provided with a slot, and thelocking-tongue f, substantially as shown and described.
